- 摘要:
- 以“金冠九号”番茄为试材,利用日光温室不同施肥处理微区试验,研究了不同施肥处理对番茄氮素积累、分配比例及肥料利用率的影响,以期探明氮肥减量配施有机物料在设施番茄上的应用效果。结果表明:与100%CF(纯化肥)处理相比,75%CF+25%VM(蚓粪)、75%CF+25%S(秸秆)处理显著增加了番茄不同部位的生物量、开花坐果期番茄中的氮含量和累积量、盛果期果实中氮素分配比例和偏生产力、农学效率和氮肥当季利用率。与100%CF处理相比,50%CF+50%VM显著提高了盛果期设施番茄的生物量、增加了开花坐果期和盛果期果实中的氮积累量。与100%CF处理相比,50%CF+50%S、100%VM、100%S处理均不同程度的降低了开花坐果期和盛果期设施番茄的生物量、氮在果实中的积累及氮素的偏生产力、农学效率和氮肥当季利用率,但仍然促进了氮素向果实中的分配。综上,75%CF+25%VM处理提高增加了番茄的生物量、提高了氮素积累量,促进了盛果期茎、叶中的氮素向果实中转移和分配,提高了氮素利用率,该研究为设施番茄的科学施肥提供了参考依据。
- Abstract:
- To clarify the effect of nitrogen fertilizer reduction and organic materials replacement on greenhouse tomato,the nitrogen accumulation,distribution and utilization efficiency of ‘Jin-Guan No9’tomato were studied in a solar greenhouse micro-experiment with different fertilization treatments.The results showed that 75% chemical fertilizer (CF)+25% vermicompost (VM) and 75% CF+25% straw (S) treatments significantly increased the biomass,nitrogen content and accumulation of tomato fruit in flowering and fruit setting stage,distribution of nitrogen of fruit,nitrogen partial factor productivity(NPEP),agronomic efficiency(AEN) and utilization efficiency of the season (NUE) in full fruit stage while compared to those of 100% CF treatment.Compared with 100% CF treatment,50% CF+50% VM treatment significantly increased the biomass at full fruiting stage,accumulation of nitrogen in fruit at flowering and fruit setting stage and full fruiting stage.Compared with 100% CF treatment,50% CF+50% S,100% VM and 100% S treatments decreased biomass at flowering and fruit setting stage,accumulation of nitrogen in fruit,NPEP,AEN and NUE,but it still promoted the distribution of nitrogen to the fruit.In conclusion,75% CF+25% VM treatment increased the biomass of tomato and nitrogen accumulation,promoted nitrogen transfer from the stems and leaves to full fruiting stage,and improved the NUE.This study provided a theoretical basis for scientific fertilization of greenhouse tomato.
